Medical inductor coils are commonly used as small components in the medical industry, but they play an important role. Do you know how many types of medical inductor coils there are? Today, let’s briefly discuss several types of medical inductor coils.
- Ferrite Core and Iron Powder Core Medical Inductor Coils
The inductance of medical inductor coils is directly related to the presence of a magnetic core. Inserting a ferrite core into a hollow medical inductor coil can increase the inductance and improve the quality factor of the medical inductor coil.
- Copper Core Medical Inductor Coils
Copper core medical inductor coils are widely used in the ultra-short wave range. The inductance can be changed by rotating the orientation of the copper core in the medical inductor coil, making it very convenient and durable.
- Single-Layer Medical Inductor Coils
Single-layer medical inductor coils are wound one by one with insulated wire on a paper tube and a wooden frame. For example, the medical inductor coil of a wave antenna in a transistor radio.
- Alpha Medical Inductor Coils
Alpha medical inductor coils are double-layered, and the winding direction of the two layers is the same, either clockwise or counterclockwise. It can be understood as the first layer is wound from the outside to the inside and then the second layer is wound from the inside to the outside. However, in the actual production process, the winding is not carried out in this exact sequence.
- Honeycomb Medical Inductor Coils
If the plane of a honeycomb medical inductor coil is not parallel to the rotation plane but intersects at a certain angle, it is called a honeycomb coil. The number of times the metal wire bends back and forth after one revolution is usually referred to as the number of bending points. Honeycomb windings have the advantages of small volume, low distributed capacitance, and high inductance. Honeycomb coils are all wound using honeycomb winding machines. The more folding points, the smaller the distributed capacitance. The inductance of ferrite core and iron powder core coils is related to the presence of a magnetic core. Inserting a ferrite core into a hollow coil can increase the inductance and improve the quality factor of the coil. Copper core inductor coils are widely used in the ultra-short wave range. The inductance can be changed by rotating the position of the copper core in the coil, making it convenient and durable.
